Benefits of technology

The patent integrates the skills of a human operator with those of a computer to identify features. This combines the creativity, flexibility, and judgment of a human with the speed and accuracy of a computer. The technical effect is an improved system that benefits from the strengths of both human and computer capabilities.

Problems solved by technology

For Class I, neutrocclusion, the molar relationship is normal but other teeth may have problems such as spacing, crowding, or over- or under-eruption.
Recent studies in orthodontics indicate that there are persistent inaccuracies and inconsistencies in results provided using conventional 2-D cephalometric analysis.
The sizable amount of measured and calculated data complicates the task of developing and maintaining a treatment plan and can increase the risks of human oversight and error.

Embodiment Construction

[0092]In the following detailed description of embodiments of the present disclosure, reference is made to the drawings in which the same reference numerals are assigned to identical elements in successive figures. It should be noted that these figures are provided to illustrate overall functions and relationships according to embodiments of the present invention and are not provided with intent to represent actual size or scale.

[0093]Where they are used, the terms “first”, “second”, “third”, and so on, do not necessarily denote any ordinal or priority relation, but may be used for more clearly distinguishing one element or time interval from another.

[0094]In the context of the present disclosure, the term “image” refers to multi-dimensional image data that is composed of discrete image elements. For 2-D images, the discrete image elements are picture elements, or pixels. For 3-D images, the discrete image elements are volume image elements, or voxels. The term “volume image” is con...

Abstract

A method, executed at least in part by a computer, acquires three-dimensional data from scans of maxillofacial and dental anatomy of a patient and computes cephalometric values from the acquired three-dimensional data. The method processes the computed cephalometric values and generates metrics indicative of tooth positioning along a dental arch of the patient. The generated metrics are analyzed to calculate desired movement vectors for individual teeth within the dental arch. The calculated desired movement vectors are displayed, stored, or transmitted.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application Ser. No. 62 / 550,013 filed in the names of Shoupu Chen et al. on Aug. 25, 2017 and entitled “METHOD OF OPTIMIZATION IN ORTHODONTIC APPLICATIONS”, which is incorporated herein in its entirety by this reference.FIELD OF THE INVENTION[0002]The present invention relates generally to image processing in x-ray computed tomography and, more particularly, to biometrics analysis from 3-D images for guidance in orthodontic treatment.BACKGROUND OF THE INVENTION[0003]Cephalometric analysis is the study of the dental and skeletal relationships for the head and is used by dentists and orthodontists as an assessment and planning tool for improved treatment of a patient. Conventional cephalometric analysis identifies bony and soft tissue landmarks in 2-D cephalometric radiographs in order to diagnose facial features and abnormalities prior to treatment, or to evaluate the progress of trea...
